buggy board with a stool? i know it exists...

[oobs]

seems like it might be a good idea. can anyone tell me what it is/where to find it? am having no luck so far googling. can't even remember what buggy it was attached to...

here you go

or this one

This one?

It only fits on prams with a rear axle though. Not sure I've seen ones with with stools on for stroller type ones though.

thanks for those links. alas my britax vigour 4+ isn't on the list of suitable pushchairs and the other is out of stock

any more suggestions??
